A six-issue 1990 comic book series. The comics follow the Men In Black, a secret organization that polices supernatural and extraterrestrial beings on Earth. The story centers on new agent Jay, whose partner Kay indoctrinates into the Agency and slowly works on getting him into the proper mindset. Other characters include Zed (who is never seen, and may or may not be a computer), and Ecks, who goes rogue.

This comic book was eventually adapted into the ''Film/MenInBlack'' film series and [[WesternAnimation/MenInBlack cartoon]].

The series was published by Aircel Comics, an imprint of Malibu Comics, which was eventually bought out by Creator/MarvelComics, which went on to publish three of its own one-shot ''Men in Black'' comic books (they were based on the live-action films, rather than the original comics, however; the company did bring creator Lowell Cunningham back to write them and also reprinted the very first issue of ''[=MiB=]'', though).

!! Tropes included:
%%* One of the stories was about a group of kids playing [[{{Tabletop RPG}} a Dungeons And Dragons clone]] who found an ancient mystical artifact and used it as their 20-sider. (They didn't know it was magic, they just thought it was cool-looking.) When one of them casts a "summon demon" spell, an actual demon appeared and destroyed half their house, and most of the town they lived in.
* FantasyKitchenSink: Unlike its film and animated adaptations, the Men in Black also monitors {{mutants}}, [[OurDemonsAreDifferent demons]], and other paranormal creatures.
* HeelFaceTurn: Agent X
* {{Jerkass}}: K, which might surprise people who are only familiar with the films.
* KnightTemplar
* ShortRunners: The original run was three issues. When TheMovie came out, three more MIB comics were made - one a straight retelling of the film, one taking place between movies 1 and 2, and only ''one'' a continuation of Lowell Cunningham's original miniseries.
* TheMenInBlack: Duh.
* TheNewRockAndRoll: Seemingly parodied in the third issue, in which a game of a faux-D&D actually causes a demon to breach our reality.
* VillainProtagonist: K all over. He neuralizes an entire street with abandon, leaves J to deal with a grieving mother and, in a later issue, [[spoiler:brainwashes a neuralized hick into climbing a clock tower with a rifle, then committing suicide, on his 16th birthday. Why? "For insurance."]] [[WellIntentionedExtremist All for the greater good, of course.]]
* WellIntentionedExtremist: K. He genuinely believes that keeping the paranormal secret is for the "greater good".
